nHE T PREV NTmG ROCKING .LOCK FOR BICYCLES.

Application filed October 7, 1826, Serial No. 140,176, and' in FranceOctober 21, 1925.

The invention' concerns a quick-acting rocking device, to prevent thetheft of any bicy'cle on which it has been itte'd, by eii'ectuallylooking either the front or the back wheeh g i The annexed drawings showa preferred cnbodimentof the invention, in which:

Fig. 1 is a perspective View of the topmost portion of a bioyclefront-tork fitted with the rocking lock.

Fig. 2 is a cross section `of the fork along the line 1-1 above'thelock, showing a plan of said lock.

The rocking' lock conprises two small boxes A and B, each forned bycutting or stanping the metal which is atterwards bent so as to have nooverlapping parts but the moveable ones. i V v The small boxes are thenbolted, screwed or riveted one on each branch of a front or rear bicyclefork. i

The box A contains a small lock of 'any known automatic catching system,actuated by the noveablepiece C placed inside the housing K; a key Dacts upon the catch E When it is desired to open the lock.

The box B contains only the recalling de- Vice for the locking rod F,and its fixed stop C. The lock Fis made ot' a cylindrical rod on the rodF. This axle bears the (coled) spring H shewn on Fg. 2 in dotted linesand'which is itself fixed at one end on the axle` G and atthe other endon the side of the box B. i

he rocking lock Works as follows:

When the bicycle is in use, the lock occnpies, through the action of thespring H,

the Vertical positionshewn on Fig. 1 in clotted lines; it is kept inthat position by the When the bioycle is no longer in use, the rod Fisraised by hand, swivelling on the conbiiation of a looking tted withan axle G placed perpendicularly' axle'G, and engaging between twospokes I and I' of the wheel J (in the manncrshewn by the' arrow) inthis 1notion,'the spring H has set itself and the end of the lock F hasi e cone against the spring stop C, placed at the top part of thehousing K; 'this contact i has automatically causecl the release of aspring actuating the catch E, which is pushed out of the box A in thelower portion of the housing K, where it remains fur-` ther seoured by asmall ledge; in this position, the lockF is kept securely in the.housing K of the box A and the wheel J cannot rotate any longer.

To free the wheel, it is only necessary, with thekey D, to bringjback,by compressing of the spring actuating it, the catch E, 6

inside the box A. The rod F, thus set free, and urged by the spring H,resuines quickly and automatically' its Vertical position against thestop C'. i

This rocking lock, light yet strong, and sure in its action, enables thecyclist to leave his nount 'Unattended without risk of theft.

I declare that What I claim is Ina theft preventing lock forbicycles,the

I rod, a first box 7 fixed on one of the branches of a for-k of thebicycle, said box containing a lock'key operated' to nnlocking,position, being closed at itsvtop to protect said lock and open at itsbottom to receive one end ot' said locking 7 rod, aseconcl box fixed onthe other branch of said fork, an axle novably nounted in said' secondbox and projecting froni the front face thereot having its projectingendfixed to the other end of said looking rod, so

`and a' recalling device within said second box to retract said lookingrod.

In testimony whereof I have afiixed my signature.

EDOUARD soULLIERn.
